Toxic Gauntlet - Marble game in progress

Hello, I am Michael Holton of Holtron Games. This is "Toxic Gauntlet", a marble/pick-up game. Roll the marble around and pick up the "Toxic" cubes. 90 second game play. Player must try and beat their best score. Every ten pick-ups will cause the gauntlet to rotate, putting the player on a different map. The player that learns the gauntlets the fastest will know which pick-up should be their tenth. If planned correctly, the player can land on a gauntlet with mega-point-pick-ups.
I am in dire need of input.
Please let me know what you think. Thanks, Holtron
